Certified to insulate the walls of older New Zealand homes

Insulmax® is the only Retrofit Wall Insulation Method to be CodeMark certified. CodeMark Certification is administered by the N.Z Government and is the highest form of product assurance in New Zealand & Australia. CodeMark certification is only awarded to products that have high levels of quality management and are compliant with the New Zealand Building Code.

Peace of mind knowing that the job has been done right

High resolution infra cameras are used after every installation of Insulmax® and are able to “see” the slightest difference in temperature radiating from your walls. Their sensitivity can even detect the temperature differences caused by structural timbers or the presence (or absence) of insulation.

Independently audited assuring our high quality standards

Insulmax® is the only retrofit wall insulation company in New Zealand to be independently audited by AsureQuality. This ensures our high standards of quality are always met.

Why renovate to insulate?

The cost, hassle and mess of removing walls to add insulation has, for years, been the daunting reason why many people continue to live in uninsulated cold homes. Most DIY’ers take weeks, months or even years to insulate their walls the old fashioned way and it’s an expensive job for the professionals.

The team at Insulmax® can cost effectively complete your wall insulation in about two days and leave your property spotless. Our aim is for our customers to see no sign that their walls have been insulated. There is no need to remove wall linings to upgrade your home! Add value to your home and save money using a system that European homeowners have tried and tested for decades. Our retro wall insulation system is fully certified for use in New Zealand.

Suitable for 99.9% of Older Kiwi Homes

Insulmax® cavity wall insulation has been awarded CodeMark certification to be installed for all types and styles of New Zealand homes and can be installed through almost all external claddings including: brick, weatherboard, block, roughcast (stucco) and fibro. We can also install through internal plaster board linings. Installation holes can be as small as a 10 cent coin in the mortar joint of a brick home and about the size of a 20 cent coin for timber clad homes.

Insulmax® insulation is water repellent and breathable so there is no requirement for building paper and it is manufactured not to absorb or wick water so it can be installed directly behind masonry. Our trained and licensed installers will finish your exterior cladding to a durable & weathertight finish. We aim to leave no signs that the walls of your property have been insulated. You’ll feel the benefits immediately and our 50 year product guarantee means those benefits will continue for years to come !
